Z Greek Posted October 18, 2011 Share Posted October 18, 2011 Guys, I am building a 3.1 liter engine for my 74 260Z. My goal is to make a decent amount of power, yet look as close to stock under the hood as possible. Research, internet shopping, etc., left me with the following combination: N42 Block VO7 Crank KA24 pistons P79 head 240Z rods, polished, balanced, shot peened, arp bolts N36 intake 3 screw SU carbs The head, and intake combo leads me to my topic. I did not like the looks of the injector "divots," in the top of the intake ports, so I welded them up. So, I end up with a head with round intake and round exhaust ports. Any off the shelf gasket I can get has the cutouts for the injectors, and of course does not have the correct holes for the N36 intake manifolds. I did not feel like punching a bunch of extra holes, and still not end up with a continuous sealing surface around my intake runners. Some internet research led me to Copper Gaskets Unlimited in Phoenix, AZ. He already had a pattern for a gasket using SU manifolds, but with rectangular exhaust ports. We spoke on the phone, and I sent him an example of a gasket with the round exhaust ports I desired. From the time he received my sample, to the time I received my gasket today, was 6 days! Check out the pictures, I am thrilled with the results If anyone is interested, the fellows name is: Lani Copper Gaskets Unlimited www.coppergaskets.us Price was very reasonable $55 plus shipping Quote Link to comment Share on other sites More sharing options...
